    摘要: An image recognition method is conducted by extracting characteristic points of the pattern of an image formed by video signals from an image pickup device, within the whole or a limited area of a frame of a display, and measuring the distribution of the characteristic points of the image pattern. With this method, images can be recognized with minimal image processing time and with reduced influence of noises.

    摘要: A position detector includes a diffraction grating provided on the surface of an object, an illumination system for illuminating the diffraction grating, a detection system for detecting diffracted light diffracted from the diffraction grating, and a processing system for detecting positional information relating to the object. The illumination system emits a first pair of beams which are diffracted by the diffraction grating and interfere with each other, and emits a second pair of beams which are diffracted by the diffraction grating and also interfere with each other. The first pair of beams are incident upon the diffraction grating along a plane extending in a first direction in which the diffraction grating extends. The second pair of beams are incident upon the diffraction grating along a plane extending in a second direction in which the diffraction grating extends. The first and second directions are different from a grating line direction. The detection system detects the interfering light and generates first and second beat signals therefrom. The processing system detects positional information with respect to the first direction from the phase state of the first beat signal and with respect to the second direction from the phase state of the second beat signal.

    摘要: A device for measuring a moving distance of two relatively moving objects includes a first diffraction grating provided on one of the two objects and disposed along the relatively moving direction of the two objects, and a measuring portion provided on the other object. The measuring portion includes a second diffraction grating, a light source and a photodetecting system, wherein the light source provides lights which are projected upon two points on the second diffraction grating so that they emanate from the two points in the form of diffraction lights having different diffraction orders. The diffraction lights are directed to the same point on the first diffraction grating and are diffracted again by the first diffraction grating so that they are emitted in the same direction, and the photodetecting system is operable to detect a change in the light intensity caused due to the interference of the two lights emanating from the first diffraction grating. The device further includes a detecting system for detecting the relative moving distance of the two objects on the basis of the detection by the photodetecting.

    摘要: A light source apparatus that emits pulsed light includes an optical resonator and a modulator. The optical resonator has an optical gain medium that amplifies light and an optical waveguide. The modulator modulates an intensity of the light in the optical resonator. The optical resonator with the optical gain medium includes a plurality of optical resonators having different optical path lengths from each other to make a difference between intervals of free spectral ranges in the plurality of optical resonators, to reduce a spectral line width of the pulsed light compared to that of a light source apparatus separately using the plurality of optical resonators as an individual optical resonator, the spectral line width determined by an envelope formed by a sideband wave of an oscillation mode which is generated by the modulation.

    摘要: A switch includes a switching mechanism, an operating mechanism with a key which normally causes the switching mechanism to be in a switched-off condition when it is pulled out and to be displaced against a biasing force to be in a switched-on condition when the key is inserted, and a locking mechanism for maintaining the switching mechanism locked in the switched-on condition and releasing it from the locked condition if a load greater than a specified magnitude is applied to the key while the switching mechanism is locked such that the switching mechanism is set back in the switched-off condition. The switching mechanism may be contained in a head case attached to a main case containing the operating mechanism. The main case also includes a forcing mechanism which tends to force the switching mechanism in the switched-off condition. Normally when the head case is attached to the main case, the forcing mechanism is released from its forcing function but when the head case is removed from the main case, the forcing mechanism functions to displace the switching mechanism into the switched-off condition.
